PECIFCTION forming' part of Letters Patent No. l754;,"258, dated March 8, 1904.

Application filed November 25, 1902. Serial No. 182,752. (No model.) I

` To all whom t may concern.:

Be it'known that I, JULIEN EUGENE TINKER, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, ha've invented a new and useful Pipe-Coupling, of which the following is.

a specification.

This invention relates to joints or couplings for pipes and tubing; and it has for its object to provide a lock-joint or coupling whereby the ends of the pipes or tubes may be united quickly and conveniently with the coupling member in such a manner as to avoid the possibility of longitudinal displacement, and hence with the ability to resist high pressure.

My invention consists in the improved construction of the interlocking pipe ends and in the combination vtherewith of locking or coupling members, all constructed and arranged as will be hereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a sectional view illustrating my invention applied tea' T-couplinfr.l :il Fig. 2 is a sectional viewtaken on the line'2'2 in Fig. 1. Fig. 3 is a side view of a couplingring` used in connection with the device. Fig. 4 is an end view of the said coupling.

Correspondingparts in the several figures are indicated by similar numerals of reference. v

The pipesor tubes 1 that are to be connected by ineens of my improved coupling device are prepared for being thus connected by providing the ends thereof with undercut portions 2, the ends of the pipes being trimmed to form L-shhped lugs or rather lugs 3, which are L-shaped when seen from the'edge of the pipe.

' In Fig. l a T coupling has been. shown. This is prepared for the reception of the pipe ends by providing its4 arms or branches with openings 15 of an interior diameter exactly ,corresponding with the exterior diameter ofthe pipes, and with beveled ends 14 to engage beveled rubber gaskets 15, seated Within annular flanges 16 of coupling-plates 17. The branches of the coupling. are also provided with perforated lugsh 18 for the passage of bolts 19, whereby they are connected with said coupling-plates. The inner ends 'of the lopenings 13 are enlarged -to form shoulders 20.

These shoulders serve as seats for the coupg that of the enlarged inner ends of the openings 13. In order, however, to permit of the insertion of the said.couplingrings through the openings or bores 14, the said rings'are reduced on diametrically oppositev sides, as

shown at 22, the reduced portions being rounded or beveled, as shown at 23. Said couplingrings are also provided with 'undercut notches 211 and with overhanging lugs 25 corresponding with and adapted to engage the lugs 3 and the notches 2 of the pipe ends. engaged, the coupling-rings seated upon the shoulders 20 of the inner ends of the bores 14 will positively preent the displacement in an outward direction of the pipes when the latter are mounted and the bolts 1 9 are tightened as shown in Fig. 1 of the drawings.

It is obvious that the principles of my invention-are capable of being applied to Ls or to four-Way couplings in precisely the same manner as they have been herein shown as applied to T-couplings, there being no change Whatever in the means required for connecting the pipe with the coupling.

I have in the foregoing described a simple and preferred form of construction of my invention; but I desire it to be understood that '1 do not limit myself to the structural details herein shown and described, but reserve.the

When thus L right to any changes and modifications which may be resorted to without `departing from the spirit and scope of my invention and without detracting from the utility of the same.

Having thus described my invention, I claim- Apipe-coupling comprising tubular members, said members being provided at their ady .jacent ends with undercut notches and overacompressble gasket seated within said Bange hanging lugs, said lugs and notches of the tuand engaging the end of the sleeve, and conbular members being nterlocked to prevent necting means. longitudinal displacement, and one of said tu- In testimony that I vclaim the foregoing as I5 5 Ybular members being of an extreme diameter my own I have hereto aixed my signature in xceedinghat of the ther, a eouplig-slfeeve the presence of two witnesses.
